Results and Benefits
The greatest benefit to the lighting upgrade is significantly
improved visibility and therefore, driver safety. The high
color rendering (70) and cooler color temperature (4000K)
LED light provides far superior visibility, allowing drivers to
see “real” colors within the tunnel. In contrast, the old low
pressure sodium lamps (2000K, 20 CRI) caused everything
to look yellow and only provided one brightness level. The
T-Max configuration and layout is modeled to provide optimal
visibility along the Túnel de la Vila Olímpica Barcelona.
“We partnered with Lumileds to
provide luminaires that deliver
exceptional output, use 40% less
energy, and will last up to 25 years.”
— Eduardo Serna
Carandini
Many tunnels throughout Europe feature centerline tunnel
lighting. Unfortunately, when maintenance is required,
both lanes of traffic must be shut down. With the side-
based illumination, one lane of the Túnel de la Vila Olímpica
Barcelona can be kept open at all times.
Finally, the luminaire and LEDs deliver high reliability with
rated lifetime of 100,000 hours (25 years). If maintenance
of the driver is required in that period, it is performed
separately from the light module. The upgrade has reduced
the lighting electricity cost by 40%. Now that one tunnel has
been upgraded to T-Max LED lighting with LUXEON M LEDs,
Barcelona is receiving positive feedback from drivers.
Solution
With multiple years of experience in tunnel lighting, Carandini
brought a custom design to the tunnel. Working with Lumileds
and choosing the LUXEON M LED for its consistency of light
output, high reliability and ultrahigh efficacy, the Carandini
T-Max fixture provides 10,000 lm of light inside el Túnel
de la Vila Olímpica. The T-Max has 11 different optical
configurations to meet a variety of needs including lighting
from one side. At the entrance and exit of this 1.5 km (1 mile)
tunnel, stacked fixtures are used to provide 40,000 lm output.
The luminaires utilize 4000K color temperature at a color
rendering index of 70. The luminaires are evenly spaced for
maximum uniformity.
“Safety drives the design in tunnel
lighting. We can drastically improve
safety today by precisely modeling
conditions and providing the
exceptional light quality of LED lighting.
— Francesc Palma
Carandini
The T-Max luminaire is a completely sealed unit with separate
driver system that can be mounted together or separate from
the light module. In this tunnel, the light module is mounted
30 cm above the drivers, allowing improved heat dissipation
from the luminaire. Because the LEDs and other electronics
are fully protected in a sealed, IP66 rated housing, the fixtures
and drivers can be high-pressure spray washed as needed.
The Carandini T-Max
fixtures uses LUXEON M for
its consistency of light output,
high reliability and ultrahigh
efficacy.
